The authors teach an astronomy unit in their seventh-grade course that they find never fails to motivate and stretch the imagination. The questions students ask are wonder-full: "What was here before the universe?" "If there was nothing before the Big Bang, where did energy and matter come from?" "Does the universe have a boundary, and if it does, what is beyond its edge?" "If all matter expanded from a space about the size of a walnut, why is there no center to the universe?" The students' sense of scale is also stretched. They have difficulty comprehending the vast distances associated with the universe, asking "If two galaxies pass through each other, won't their stars collide?" The star maps commonly used to teach astronomy draw stars close together and in two dimensions. When viewing these maps, almost everyone uses more concrete, two-dimensional thinking to interpret the position of the stars. The maps provide no human scale reference point by which to make those distances meaningful. The authors have developed a project that helps students think in both two and three dimensions, displays the relative distances between Earth and stars, and introduces students to the constellation myths of diverse cultures.
